It opens with a shot of a cross, to remind us that Justin Bieber is a Christian. Is it a song? Is it a video? What is it? What’s happening in this thing called “Holy,” a song (?) sung by Justin Bieber with a rap part by Chance the Rapper. Wilmer Vilderrama puts in an appearance. Justin has a black girlfriend or wife, they’re in deleted scenes from “Days of Heaven,” I don’t know. He gets laid off, they get picked up by Wilmer, who’s a soldier, and it’s all “holy holy holy.” It’s a headscratcher in the pantheon of Bieber releases. Much ado about nothing. The song might be better without the video. Teens will decide.
